Morphology

material + witness

The meaning 'a witness whose testimony is essential and directly relevant' is directly and compositionally derived from 'material' (having direct relevance or importance) modifying 'witness' (a person who testifies). This adjective+noun pattern is regular and cross-linguistically common, so a B1 learner who knows both constituents should be able to infer the MWE meaning, despite its legal register.

Etymology

The term material witness comes from law where material means 'important' or 'has to do with the case' and witness is a person who saw or knows something. So a material witness is someone whose testimony really matters to the case.
